hi everyone! school starts tomorrow! i am excited/nervous:D:uhoh3:. As I was going through some math problems,I encountered this one problem and I am a bit confused! Here is the question:The physician has ordered a bolus of 400 mL over 4 hours .After 2 hours, 300 mL remain in the bag. Hospital policy allows a 25% increase in the IV rate to compensate for the slow infusion. a. what is the new rate?My instructor said to solve for the mL/hr : 400mL/4 hrs= 100mL/hr and then she did this: 100mL * 1.25= 125 mL/hr. Now my question is: why 1.25?does it have something to do with percent? Is that the reason why we she put 1 in front of. 25?? I thought at first that to solve for the new rate,I should do this: 300mL/ 2hrs??b. how long will the balance of the infusion take?125 mL/hr = 300mL/xx= 2.4 hrs. HELP!
